This book covers all the necessary aspects, from breaking up the cells (homogenization), via a variety of separation techniques (the isolation and fractionation chapters), to characterization of the separated organelles. 410 0$aPractical approach series. 606 $aSubcellular fractionation$vHandbooks, manuals, etc 606 $aSubcellular fractionation$vLaboratory manuals 615 0$aSubcellular fractionation 615 0$aSubcellular fractionation 676 $a571.6/5 701 $aGraham$b J.
